The tractor and two wheeled trailer combination being the most popular load carrying vehicle of the Indian farms, is often susceptible to serious accidents due to lateral roll over. A simple PIC based lateral stability monitor was developed from basic principles for the tractor trailer combo. The system uses a commercial tilt sensor to detect the roll angle, a potentio-metric sensor to sense the turning radius and a hall effect sensor to measure the speed of travel. The control code calculates the lateral stability ratio and compares it to the stability limits. The code cautions the operator visually and audibly to take evasive action well before instability occurs. The monitor was tested in the field under various sloping terrains, turning speeds and payloads, and was found to function satisfactorily.
